Interrupt acknowledge input (internal pull-up); when this signal is asserted the
interrupt vector in register S3 will be available at the bus Port if the ENI flag is set.
Serial data input in long-distance mode.
Interrupt output (open-drain); this signal is enabled by the ENI flag in register S1.
It is asserted when the PIN flag is reset. (PIN is reset after 1 byte is transmitted or
received over the I
Register select input (internal pull-up); this input selects between the control/status
register and the other registers. Logic 1 selects register S1, logic 0 selects one of
the other registers depending on bits loaded in ESO, ES1 and ES2 of register S1.

RD is the read control input for MAB8049, MAB8051 or Z80-types. DTACK is the
data transfer control output for 68000-types (open-drain).

WR is the write control input for MAB8048, MAB8051, or Z80-types
(internal pull-up). R/W control input for 68000-types.
Reset input (open-drain); this input forces the I
state; all flags are reset, except PIN, which is set. Also functions as strobe output.
